This change removes a duplicate 'Comment' field from the customer rating form. The original implementation relied on a module not directly connected to the Helpdesk module, causing an issue. This reversion ensures the form functions correctly and avoids redundant data entry.

This reverts commit de8dd6703393ec83fbdbe76dd0c69654ac72e662 because the publisher_comment field in `rating.rating` model is defined in `portal_rating` module and that module is not in the dependencies of helpdesk module.
